Objective To evaluate the effectiveness and safety of somatostatin and the analogue-octreotide in preventing post-ERCP pancreatitis. Methods We searched Cochrane Clinical Trial Register （Issue 1, April, 2004 ）, MEDLINE （1966- April, 2004）, EMBASE （1985- April, 2004）, CBM disc （1970- April, 2004） and The Clinical Trial Register of Chinese Evidence-Based Medicine Center and handsearched the related journals to identify Randomized Controlled Trials （RCT）of somatostatin and octreotide in post-endoscopic retrograde chnlangiopancreatography pancreatitis（PEP）prevention. Systematic review was conducted using the method recommended by The Cochrane Collaboration. Results Thirty-one trials involving 4 728 patients undergoing ERCP were included. Meta-analysis showed that the incidence of post-ERCP pancreatitis [ OR 0.33, 95% CI 0. 20 to 0. 54; P =0. 000 01 ; NNT =13] was significantly reduced by somatostatin. Octreotide could only reduce the incidence of hyperamylasemia [ OR 0. 54, 95% CI 0. 38 to 0. 77 ; P =0. 000 7 ]. The inci- dence of PEP, severe PEP and post-ERCP abdominal pain could not be reduced by octreotide. Conclusions Somatostatin can prevent post-ERCP pancreatitis. Four trials are of high quality in the 12 included studies and the results are consistent with the sensitive-analysis, so it is credible to some extent. However, existing evidence does not support that octreotide can reduce the incidence of PEP, so it is not recommended for this indication. Sensitive-analysis even showed that octreotide could increase the incidence of PEP. Therefore, whether it is necessary to carry out further clinical trials should be considered with caution.
Objective To find the most effective treatment for a patient with difficult selective biliary cannulation (DSBC) during endoscopic retrograde cholangiopancreatography (ERCP) by EBM practice. Methods Evidence was retrieved from The Cochrane Library (Issue 1, 2010), ACP online, NGC (1998 to June 2010), PubMed (1950 to June 2010), and CBM (1994 to June 2010). The collected evidence was then graded. Results After preliminary research, we identified 18 relevant articles. The evidence showed that pre-cutting technique could increase cannulation success rates in DSBC and was safe, effective, and time-saving for an experienced endoscopist. Pancreatic duct occupation was easier to perform than pre-cutting technique and could also increase selective cannulation success rates in DSBC. According to the evidence, together with endoscopist’s experience and the preference of the patient and his family, needle-knife precut papillotomy was performed. Successful selective biliary cannulation was accomplished after pre-cutting. Conclusion The current evidence suggests that pre-cutting technique and pancreatic duct occupation could increase selective cannulation success rates in DSBC. Patients’ condition and endoscopist’s experience should be considered properly before the operation.
Objective To explore the value of endoscopic retrograde cholangiopancreatograph (ERCP) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of pancreatic duct stones. Methods A retrospective collection of 28 patients with chronic pancreatitis and pancreatic duct stones admitted to the Department of Gastroenterology from January 2010 to August 2021 was performed. According to the treatment of patients, they were divided into ERCP direct stone extraction group and ESWL combined ERCP stone extraction group. We compared the treatment effects of the two groups of patients, including the success rate of stone extraction, postoperative complications of ERCP, postoperative symptom improvement, and so on. Results Among the 28 patients, 19 cases underwent ERCP direct stone extraction, and 9 cases underwent ESWL combined with ERCP stone extraction. In the ERCP direct stone extraction group, 7 cases (36.84%) were completely extracted, 1 case was partially extracted (5.26%), and 11 cases (57.89%) failed to extract and only placed stents and drained; 5 cases (26.32%) had elevated white blood cells at 6 hours postoperatively, C-reactive protein increased in 4 cases (21.05%), 3 cases (15.79%) were diagnosed as ERCP-related pancreatitis, and 2 cases (10.53%) were diagnosed as hyperamylaseemia. The abdominal pain symptoms were completely relieved in 14 cases (73.68%) during a follow-up period of 3 to 6 months. The body mass of 17 cases (89.47%) increased in the 6 months after stone extraction. ESWL combined with ERCP had complete stone extraction in 5 cases (55.56%), partial stone extraction in 3 cases (33.33%), and failure in stone extraction and only stent drainage in 1 case (11.11%). One case (11.11%) had elevated white blood cells at 6 hours postoperatively, and 1 case (11.11%) had elevated C-reactive protein . One case (11.11%) was diagnosed with ERCP-related pancreatitis. One case (11.11%) got abdominal pain and transient hematuria during ESWL, which resolved spontaneously 3 days later. After 3 to 6 months of follow-up, 9 patients (100%) had complete relief of abdominal pain symptoms, and the body mass of 9 patients (100%) increased in the 6 months after stone extraction. The stone clearance rate of the ESWL combined with ERCP stone extraction group was higher than that of the ERCP direct stone extraction group (P=0.033), but there was no statistically significant difference between the two groups in terms of ERCP-related complications, relief of abdominal pain, and weight gain (P>0.05). Conclusion ESWL combined with ERCP in the treatment of chronic pancreatitis complicated with pancreatic duct stone extraction is more effective than ERCP direct stone extraction.
Objective To evaluate the role of endoscopic retrograde cholangio-pancreatography(ERCP)in diagnosis of anomalous converge of the cystic duct and prevention of bile duct injuries during laparoscopic cholecystectomy(LC). Methods From July, 1992 to June, 1999, LCs were performed in 4 500 patients with gallbladder stone or cholecystitis at our center. Preoperative ERCPs were performed in 780 of all patients (14.50%). Anomalous junctions of the cystic duct with common hepatic duct were investigated and the length and caliber of these cystic duct were measured and compared with 100 control cases. Results An overall anomalous converges of the cystic duct were found in 125(16.03%) of the 780 patients undergoing ERCP. Of 780 patients undergoing LC, 35 cases were converted to open cholecystectomy(4.5%), and various complications occurred in 6 cases (0.77%), but no death and biliary duct injuries occurred. Conclusion Various types of anomalous junctions of the cystic duct could be diagnosed precisely by ERCP before LC and the preoperative examination of ERCP may be helpful in prevention of bile duct injuries and other biliary complications in the laparoscopic time.
Objective To explore and summarize the application of minimally invasive technique to every stage of severe acute pancreatitis (SAP). Methods The treatment of 101 SAP patients admitted to our hospital between January 1995 and December 2008 were retrospectively analyzed. After calculi were removed by endoscopic retrograde cholangiopancreatograpy (ERCP) and endoscopic sphincterotomy (EST), endoscopic nasobiliary drainage (ENBD) were applied, then rhubarb liquid was perfused into gut with a nutrient canal and ultrasound-guided abdominal drainage tube were simultaneously placed at the early stage. Some patients received continuous renal replacement therapy (CRRT) at the same time. Laparoscopic cholecystectomy (LC) was performed at the subacute stage, and choledochoscope was introduced to remove parapancreatic necrotic tissues at the late stage of SAP.Results Of all the 101 cases treated by the method mentioned above, 75 cases received ERCP (or EST) and ENBD, and 31 cases underwent rhubarb liquid perfusion with a nutrient canal. Eight cases underwent continuous renal replacement therapy (CRRT). Forty-eight cases underwent LC and ultrasoundguided abdominal drainage. Thirtysix cases with infected peripancreatic tissue or abscess underwent debridement under choledochoscope 3 to 14 times at the later stage. Five cases died of multiple organ failure (MOF) and acute respiratory distress syndrome (ARDS). The hemobilia ocurred in 2 patients during choledochoscopy and was cured under direct visualization by electric coagulation. Intestinal fistula happened in 3 cases and cured by drainage. Pancreatic pseudocyst was latterly seen in 3 cases and treated by the anastomosis of cyst with jejunum through selective operation. After the hospitalization of 9-132 d (mean 24 d), 96 cases completely recovered. Conclusion Timely application of minimally invasive technique to every stage of SAP can avoid the defects of traditional operations, decrease the injury and interference to the maximum, and raise the cure rate.
Objective To discuss the value of biliary stent in treatment of malignant biliary obstruction with different pathways of bile duct stent insertion. Methods Fourty-two cases of malignant biliary obstruction whose biliary stent insertions were through operation (n=18), PTCD (n=17) and ERCP (n=7) respectively were reviewed retrospectively. Results The bile duct stents were successfully inserted in all patients through the malignant obstruction and achieved internal biliary drainage. Compared with the level of the bilirubin before operation, it decreased about 100 μmol/L one week after the stent insertion in all patients. Compared with the levels of glutamic oxalacetic transaminase, glutamic pyruvic transaminase, alkaline phosphatase and glutamyltranspeptidase before operation, they decreased 1 week after the stent insertion （Plt;0.05). The median survival time was 22 weeks. The average survival time was (32.89±33.87) weeks. Two patients died in hospital after PTCD, and the mortality was 4.76%. Complications included 8 cases of cholangitis, 3 cases of bile duct hemorrhage and 2 cases of hepatic failure. Conclusion The bile duct stent insertions through operation, PTCD and ERCP are all effective in relieving the bile duct construction with malignant biliary obstruction. Each method should be chosed according to the systemic and local condition for every patient so as to improve the safety and efficiency, and to decrease the occurrence of complications.
Objective?To assess the effectiveness and safety of diclofenac, one of the routine-used NSAIDs, in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP). Methods Firstly, the electronic searches were conducted to retrieve Randomized controlled trials (RCTs) from The Cochrane Library, PubMed, Embase, OVID, CBM, CNKI, VIP and WanFang Data. Secondly, 12 kinds of specific Chinese journals like Chinese Journal of Gastroenterology and conference proceedings were hand-searched till June 2011, and all references in all included trials were searched, too. The RCTs on diclofenac for preventing PEP were identified and retrieved. The systematic review was conducted by using methods and principles recommended by the Cochrane Collaboration. Results A total of 5 RCTs involving 675 PEP patients were included. The Meta-analysis showed that diclofenac might reduce the incidence of PEP (OR=0.41, 95%CI 0.18 to 0.95, P=0.04), but the sensitivity analysis indicated this result was not stable. No evidence showed diclofenac could reduce the incidence of severe PEP (OR=0.40, 95%CI 0.08 to 2.06, P=0.27). And no adverse reactions related to the drug were reported. Conclusion Diclofenac may be safe and effective in reducing the incidence of PEP, but it has no significant effect on preventing severe PEP. Considering the methodological and scale limitation of included studies, this conclusion still needs to be proved by more large-scale and high-quality RCTs.
Objective To analyze and explain how to treat 1 patient with post-ERCP hemobilia based on best clinical evidence. Methods We used EST and EPBD, ENBD, Hemobilia as key words to search MEDLINE （1978 ～ 2004） and CBMdisc（1978 ～ 2004） to find the best clinical evidence and evaluated the quality of evidence. Results According to the evidence, we found that endoscopic papillary balloon dilation （EPBD） or endoscopic nasobiliary drainage （ ENBD ） may be more effective and better tolerated in the treatment ofpost-ERCP hemobilia. Our patient did not receive sufficient medical treatment after hemobilia. He was not given a general assessment before surgery including liver function tests. As a result, the patient died of liver failure and its complications. Conclusions We should treat such patients promptly and efficiendy after hemobilia. We should also evaluate their general condition properly before the operation.
Objective To analyze the clinical features， common etiologies， prevention measurements of recurrent acute pancreatitis （AP）. Methods The clinical characteristics and imaging examination data of 43 patients with recurrent AP were analyzed retrospectively， which was compared with the results of 258 patients with primary AP. The recurrence etiologies were analyzed. Results There were no significant differences on the fever， jaundice， abdominal pain relief time， pancreatic local complications， and ratio of severe AP between two groups （P＞0.05）. Comparion of etiologies between recurrent AP and primary AP， cholecystitis and diet factor （alcoholic） had priority in patients with primary AP （P=0.038， P=0.006， respectively）， but the hyperlipidemic， duodenal nipple disease， and small stone in the common bile duct were the major etiologies in patients with recurrent AP （P=0.007， P=0.008， respectively）. No relapse was found within the follow up for 3 months to 2 years （the average time was 14.2 months）. Conclusion Find out the exact etiology and performe correct therapy are the key to the treatment and prevention of recurrent AP.
Objective To investigate clinical application and safety evaluation of sedative demulcent anesthesia in therapeutic endoscopic retrograde cholangiopancreatography (ERCP).Methods Totally 1660 patients underwent ERCP at the First Hospital of Lanzhou University were prospectively divided into two groups: venous sedative demulcent group (n=800, using sufentanil and midazolam and propofol continuing infusion) and conventional sedative demulcent group (n=860, using common medicine). The heart rate (HR), respiration (R), blood pressure (BP) and peripheral oxygen saturation (SpO2) of pre-anesthesia, post-anesthesia, during operation and after analepsia in every group were detected. The narcotism was evaluated by Ramsaymin grading method and the related adverse reactions such as cough, restlessness, harmful memory, and abdominal pain after operation were recorded. Results Compared with conventional sedative demulcent group, vital signs of patients in venous sedative demulcent group were more stable. For postoperative adverse reactions, abdominal pain, abdominal distension and nausea and vomiting were respectively 4.4%(35/800), 2.6%(21/800) and 3.6%(29/800) in venous sedative demulcent group, which were respectively higher of the incidence of 36.3%(312/860), 49.0%(421/860) and 53.0%(456/860) in conventional sedative demulcent group (P＜0.01). The postoperative satisfaction and adverse reactions recall between venous sedative demulcent group and conventional sedative demulcent group was respectively significant different (96.9% vs. 2.9%, 4.8% vs. 97.9%, P＜0.01). Conclusion Sufentanil and midazolam and propofol continuing infusion have good effect of sedative demulcent anesthesia, which can be widely used.
